Endpoint and authentication

Base URL:

https://api.apixo.ai/api/v1

Method	Endpoint	Purpose
`POST`	`/generateTask/wan-3-0-video`	Submit a generation task
`GET`	`/statusTask/wan-3-0-video?taskId={taskId}`	Poll task status and retrieve results

All requests require your APIXO API key:

Authorization: Bearer YOUR_API_KEY

Submit requests also require:

Content-Type: application/json

Copy-paste async quickstart

This minimal request submits a text-to-video task and returns a taskId.

curl -X POST "https://api.apixo.ai/api/v1/generateTask/wan-3-0-video" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "request_type": "async",
    "input": {
      "mode": "text-to-video",
      "prompt": "a cinematic product reveal with smooth camera movement and premium studio lighting",
      "resolution": "480p",
      "aspect_ratio": "auto",
      "duration": 5,
      "sound": true
    }
  }'

Successful response:

{
  "code": 200,
  "message": "success",
  "data": {
    "taskId": "task_12345678"
  }
}

Save the taskId; you need it to poll for the final result.

Poll for result

curl -X GET "https://api.apixo.ai/api/v1/statusTask/wan-3-0-video?taskId=task_12345678" \
  -H "Authorization: Bearer YOUR_API_KEY"

Wan 3.0 Video input parameters.

Show properties

string

required

Generation mode. Supported values: text-to-video, image-to-video, reference-to-video.

string

Prompt text. Required for text-to-video; optional for image-to-video and reference-to-video. Required prompts cannot be empty after trimming.

string

default:"1080p"

Output resolution tier. Supported values: 480p, 720p, 1080p.

string

default:"auto"

Output aspect ratio. Supported values: auto, 16:9, 4:3, 1:1, 3:4, 9:16. Use aspect_ratio, not ratio.

integer|string

default:"5"

Output duration in seconds. Supports -1 for smart duration, or integers from 2 through 30, including numeric strings such as "8". Decimal values such as -1.0 are rejected.

boolean

default:"true"

Whether the generated video should include audio.

boolean

default:"false"

Whether to add a watermark.

integer

Optional random seed. Supported range: 0 to 2147483647. A fixed seed improves reproducibility, but identical seeds do not guarantee identical outputs.

string[]

Image URLs. Required for image-to-video with 1-2 images, where image_urls[0] is the first frame and image_urls[1] is the optional last frame. Optional for reference-to-video with up to 10 images.

string[]

Reference video URLs for reference-to-video. Supports up to 5 URLs when provided. Each video must be 1-15 seconds, total reference video duration cannot exceed 15 seconds, and reference video seconds are billed at the same per-second rate as the selected mode and resolution.

string[]

Reference audio URLs for reference-to-video. Supports up to 5 URLs when provided. Each audio file must be 1-15 seconds, and total reference audio duration cannot exceed 15 seconds. Audio is not billed separately.

string[]

File inputs for reference-to-video. Supports at most 1 URL. Cannot be used together with link_urls.

string[]

Web link inputs for reference-to-video. Supports at most 1 URL. Cannot be used together with file_urls.

Mode	Required input	Unsupported media fields	Billing note
`text-to-video`	`prompt`	`image_urls`, `video_urls`, `audio_urls`, `file_urls`, `link_urls`	Output duration is billed per second.
`image-to-video`	`image_urls` with 1-2 images	`video_urls`, `audio_urls`, `file_urls`, `link_urls`	Output duration is billed per second.
`reference-to-video`	At least one of `image_urls`, `video_urls`, `audio_urls`, `file_urls`, or `link_urls`	None, but `file_urls` and `link_urls` are mutually exclusive	Output duration and reference video seconds are billed per second.

Use public, directly accessible URLs for all media inputs. Video and audio durations are checked before the task is submitted.

When duration is positive and video_urls are provided, total reference video seconds plus duration cannot exceed 30 seconds. When duration is -1, the request uses smart duration and is pre-charged as 30 seconds.

Response format

Submit task response

POST /generateTask/wan-3-0-video returns a task ID when the task is accepted:

integer

API status code. 200 means the task was accepted.

string

Human-readable status message.

string

Unique task identifier used with the status endpoint.

Status response fields

string

Unique task identifier.

string

Current task state: processing, success, or failed.

string

JSON string containing generated video URLs in resultUrls. Present when state is success.

string

Machine-readable failure code. Present when state is failed.

string

Human-readable failure message. Present when state is failed.

integer

Task creation timestamp in Unix milliseconds.

integer

Task completion timestamp in Unix milliseconds. Present after completion.

integer

Processing duration in milliseconds. Present after completion when timing data is available.

Webhook callback mode

Use callback mode when your backend should receive the final result automatically instead of polling.

curl -X POST "https://api.apixo.ai/api/v1/generateTask/wan-3-0-video" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "request_type": "callback",
    "callback_url": "https://your-server.com/webhooks/apixo",
    "input": {
      "mode": "reference-to-video",
      "prompt": "create a polished product video using the references",
      "image_urls": [
        "https://example.com/ref.png"
      ],
      "resolution": "720p",
      "aspect_ratio": "auto",
      "duration": -1,
      "sound": true
    }
  }'

The callback payload uses the same top-level shape as status polling with code, message, and data. Successful callbacks include the final state and resultJson. See Webhooks for delivery requirements and retry behavior.

Billing

Wan 3.0 Video is billed per second. Unit price depends on both mode and resolution.

Mode	Resolution	APIXO official price
`text-to-video`	`480p`	`$0.075 / second`
`text-to-video`	`720p`	`$0.10 / second`
`text-to-video`	`1080p`	`$0.15 / second`
`image-to-video`	`480p`	`$0.075 / second`
`image-to-video`	`720p`	`$0.10 / second`
`image-to-video`	`1080p`	`$0.15 / second`
`reference-to-video`	`480p`	`$0.10 / second`
`reference-to-video`	`720p`	`$0.15 / second`
`reference-to-video`	`1080p`	`$0.24 / second`

Billing formulas:

Request	Formula
`text-to-video` or `image-to-video` with positive `duration`	`duration * unitPrice`
`reference-to-video` with positive `duration`	`(input video seconds + duration) * unitPrice`
Any mode with `duration = -1`	Pre-charge `30 * unitPrice`; after success, final billable seconds are `input video seconds + actual output seconds`, and any difference is refunded

Input images, audio files, files, and links do not add separate billable seconds. For current route and market comparison pricing, see Pricing.

Latency and polling

Wan 3.0 Video tasks are asynchronous. Actual latency may vary by prompt complexity, duration, reference media accessibility, resolution, route queue load, and provider-side processing time.

Workload	Typical generation time	Recommended first poll	Poll interval
Text-to-video or image-to-video	Varies by prompt, resolution, and duration	60s after task creation	10s-15s
Reference-to-video with image, video, audio, file, or link inputs	Often longer than simple generation	60s-90s after task creation	10s-15s

For production workloads, use callback mode to avoid frequent polling while video tasks run.

Result URLs are temporary. Download and store important outputs promptly after task completion. Rate limits and concurrency can vary by account, API key, and route. If you receive 429, slow down requests and retry with backoff. For account-level details, see System APIs.

Errors and troubleshooting

HTTP errors

Code	Meaning	What to do
`400`	Invalid request body, missing `input`, unsupported `mode`, missing required `prompt` or media, invalid `resolution`, invalid `aspect_ratio`, invalid `duration`, or invalid media array	Fix the request before retrying
`401`	Missing or invalid API key	Check the `Authorization` header
`402`	Insufficient balance or quota	Add balance or switch account/key
`403`	Key or route cannot access the model	Check permissions and route strategy
`404`	Task not found when polling	Check the `taskId`
`429`	Rate limit or concurrency limit reached	Retry with exponential backoff
`500`	Server error or unknown task failure	Retry with backoff
`502`	Upstream error	Retry with backoff
`504`	Upstream timeout	Retry or use callback mode for long-running jobs

Validation notes

Condition	Backend behavior

Missing `mode`	Request fails before task creation.
Unsupported `mode`	Request fails before task creation. Supported values are `text-to-video`, `image-to-video`, and `reference-to-video`.
Missing `prompt` in `text-to-video`	Request fails before task creation.
Empty required `prompt`	Request fails before task creation.
Missing `resolution`	Defaults to `1080p`.
Unsupported `resolution`	Request fails before task creation. Supported values are `480p`, `720p`, and `1080p`.
Missing `aspect_ratio`	Defaults to `auto`.
Unsupported `aspect_ratio`	Request fails before task creation. Use `auto`, `16:9`, `4:3`, `1:1`, `3:4`, or `9:16`.
Using `ratio` instead of `aspect_ratio`	`ratio` is not a public Wan 3.0 field. Use `aspect_ratio`.
Missing `duration`	Defaults to `5`.
`duration` outside `-1` or `2` through `30`, or a decimal value	Request fails before task creation.
`image-to-video` without `image_urls`	Request fails before task creation.
`image-to-video` with more than 2 images	Request fails before task creation.
`reference-to-video` without any reference input	Request fails before task creation.
`file_urls` and `link_urls` used together	Request fails before task creation.
Reference video or audio shorter than 1 second or longer than 15 seconds	Request fails before task creation.
Total reference video duration or total reference audio duration over 15 seconds	Request fails before task creation.
Positive `duration` plus total reference video duration over 30 seconds	Request fails before task creation.

Task failure codes

failCode is generated from APIXO’s mapped provider error. Common values include:

Fail code	Meaning	What to do
`SensitiveContent`	Prompt or input/output content was rejected by safety checks	Change the prompt or reference media
`PromptInvalid`	Prompt was invalid or rejected by the provider	Rewrite the prompt and retry
`ImageFormatIncorrect`	Reference image format could not be processed	Use a public, direct image URL in a common image format
`RateLimited`	Provider-side rate limit was reached	Retry with exponential backoff
`Timeout`	Provider-side timeout	Retry later or use callback mode
`Unknown error`	The provider returned an unmapped failure	Retry with backoff or contact support with the `taskId`
